Summary

Here we describe a novel class of short RNAs and high-resolution ChIP-Seq data that together indicate widespread divergent transcription at mammalian promoters and suggest the existence of novel regulatory mechanisms concerning both initiation and elongation by RNA polymerase II.

Overall Design

ChIP-seq in murine embryonic stem cells for RNA polymerase II

Processing steps for GSE12680
  1. Images analysis and base calling was done using solexa pipeline and reads aligned to both mouse NCBI build 36 using ELAND.
  2. For ChIP-Seq, sequences from all lanes were extended 200bp (maximum fragment length accounting for ~100bp of primer sequence), and allocated into 25 bp bins.
  3. Genomic bins containing statistically significant ChIP-seq enrichment were identified by comparison to a Poissonian background model, using a p-value threshold of 10-9.
  4. Additionally, we used an empirical background model obtained from identical Solexa sequencing of DNA from whole cell extract (WCE) from matched cell samples (>5X normalized enrichment across the entire region).
